It'd be neat if you could find some old insulation somewhere and insulate the thing!
Years ago I knew a guy who built something like this, but he cut a hole in the floor in the corner of it and somehow underneath the stand put a 5 gal bucket that attached to the outside floor of the bottom of his stand. Well, on the inside, he had an old toilet lid/seat and built a little stool about 3 ft off the floor and well you know... the rest is history! hahaha
...I am not skilled to understand, what God has willed, what God has planned, I only know at His right hand, stands One who is my Savior....
